Benco Concentrate equipments are designed for continuous 24 hour per day operation in chemical, industrial mineral and ore processing industries. Units are supplied in two basic conﬁ gurations: bridge or centre pier mounted in diameters from 5 to 75 m.

Lift Mechanism

For bridge mounted drive heads rake lift is through a torque tower which is bolted to the main wheel and drives the rake shaft through a keyway. The rake shaft is raised and lowered by a motor driven screw jack.

For centre pier mounted drive heads, the drive head is supported by a pier and drives the rakes through a torque cage. The drive head and rake torque cage are raised and lowered by motor driven screw jacks
